Thank you for your answer.
To be clear, I don’t need to store the phone number inside a deal record.
Deal is connected to contact and contact hodls the phone number information.
I just would like to see this phone no. in deal view (in the left column). Currently for contact is visble the name, role and e-mail. I just would like to populate also phone no. too.
So if I want to call them I don’t need to click in contact details and go out from deal view. That’s it.
Any idea how to see the phone no. too?
